Orbital Marine Power

What Orbital Marine Power does

Orbital Marine Power is a UK-based tidal energy technology company founded in 2002 (originally as Scotrenewables Tidal Power Limited) and headquartered in Orkney, Scotland. The company designs and operates floating tidal stream turbines that capture kinetic energy from tidal currents, with its current flagship O2 turbine rated at 2MW+ and recognized as the world's most powerful operational tidal turbine. The proprietary platform features a 74m floating superstructure with twin 1MW turbines, retractable leg structures enabling low-cost surface-level maintenance, and 360-degree blade pitching control that captures power from both tidal directions.

The company monetizes through multiple revenue streams: UK Contracts for Difference (CfD) auctions securing 15-20 year fixed-price revenue contracts, Power Purchase Agreements with utilities including Nova Scotia Power, technology licensing to international partners (e.g., Eauclaire Tidal for Canadian deployment), and equipment supply to project developers. Its target customer base comprises national utilities and grid operators seeking predictable baseload renewable energy, provincial/state energy authorities developing domestic tidal resources, and community or remote/island energy projects. Orbital has secured a forward project pipeline of 32MW across 13 turbines in the UK and Canada, with the planned Westray Tidal Array in Orkney envisioning up to 70 turbines generating 170MW.

The business operates with approximately 30-32 staff across Orkney and Edinburgh offices, co-located with the European Marine Energy Centre (EMEC) test infrastructure. Strategic partners include TechnipFMC for global commercialization, SKF for integrated power train supply, ITM Power for hydrogen integration, and Invinity for battery storage pairing. The company is pursuing IECRE certification for its next-generation O2-X turbine (2.4MW) and is expanding into the US market, supported by approximately £25M+ in cumulative funding from crowdfunding, government grants, and strategic equity investors including Scottish Enterprise, the Scottish National Investment Bank, and TechnipFMC.

Revenue model

1. Contract for Difference (CfD) Revenue: Orbital secures long-term CfD contracts from UK government renewable energy auctions. These contracts guarantee a fixed strike price for electricity generated over 15-20 year periods, providing revenue certainty for project financing and operation.
2. Power Purchase Agreements (PPAs): Direct electricity sales through PPAs with utilities such as Nova Scotia Power for Canadian projects and UK grid operators. Revenue based on MWh generated at contracted rates.
3. Technology Licensing: Licensing Orbital's floating turbine technology to international partners like Eauclaire Tidal for deployment in global markets including Canada and the United States.
4. Equipment Supply: Supply of turbines and components for project developers. Project pipeline involves building approximately £200 million of equipment with ~70% UK supply chain content.

Core offering

Orbital Marine Power designs, manufactures, and operates floating tidal stream turbines that convert kinetic energy from tidal currents into predictable, low-carbon electricity. Its flagship O2 turbine (2MW+) is operational in Orkney, Scotland since July 2021, while the next-generation O2-X (2.4MW) is advancing through IECRE certification for deployment in the UK, Canada, and the US. The company sells and licenses its proprietary floating turbine platform and develops utility-scale tidal energy projects with grid connections.

Product overview

Orbital Marine Power offers a portfolio of floating tidal turbine products and projects. The core product is the O2 turbine, currently the world's most powerful tidal turbine at 2MW+, with the next-generation O2-X (2.4MW) in certification. The company develops tidal energy projects including the planned Westray Tidal Array (170MW) and participates in collaborative research projects (FORWARD2030, TIGER, MAXBlade) that integrate tidal power with battery storage and hydrogen production.
